Safety valves with diaphragm made of gunmetal, angle type with threaded connections
Diaphragm safety valve for the protection of small and medium-sized, intrinsically safe solar plants. The valve is characterized by a number of special features: Temperature resistance tested up to 160 °C, 100% metal design and available with different connection types up to a size of one inch. The valve is type tested according to TÜV standards for closed, intrinsically safe solar heating systems with a flow temperatures of up to 120 °C. Depending on the connection size, it is suitable for a heating output of up to 200 kW.
- Examples of use
For the protection of:
- closed-circuit, intrinsically safe solar heating systems with water or water mixtures as a heat transfer medium, with permissible supply temperatures of up to 120°C.
As these valves are completely made of metal, they can also be installed at high environmental or radiation temperatures. All materials suitable for max. temperatures up to 160°C.
- intrinsically safe, thermal solar plants
For non intrinsically safe plants and temperatures >120°C please use the safety valves 451/851bG series or 452/852bGL series.
Safety valves are set and sealed at the factory.
